The 560-foot-long Liberian tankship Julie N, carrying a
cargo of heating oil, collided with the south bascule pier of the
Portland-South Portland (Million Dollar) Bridge in Portland, Maine, on
September 27, 1996. The collision resulted in a 33-foot-long hole in
the vessel's hull beneath the waterline. About 4,000 barrels of oil
spilled into the harbor. The vessel sustained about $660,000 in damage,
and the cost for cleanup of the oil was approximately $43 million.
Repairs to the Million Dollar Bridge were about $232,000. After
investigating the accident, the National Transportation Safety Board
(NTSB) issued Special Investigation Report (SIR) 98/02 which was
adopted on May 5, 1998. A summary of SIR/98/02 is attached.
The Federal Highway Administration has been requested by the NTSB
recommendation (M-98-83) to inform, in cooperation with the American
Association of State Highway and Transportation Officials (AASHTO),
State highway departments of the circumstances of this accident and
recommend that the States evaluate the adequacy of fendering systems at
bridge piers where the systems were not designed for the type and size
of vessel currently using the waterway and may not be adequate to
protect the bridge and take corrective action as necessary.
Therefore, we request that State DOTs evaluate the adequacy of
fendering systems at bridges which have a USCG permit for navigational
clearances. This evaluation should be conducted as a part of the next
scheduled national bridge inspection. The evaluation should determine
if the bridge's fender system provides adequate protection for the
bridge or for vessels navigating through its draw. If the fendering is
found to be inadequate, an improved fendering system should be
considered. The attached summary of SIR/98/02 contains an example of an
adequate fendering system in the section titled: "Fender System for the
New Bridge."
